Electrochromic rearview mirror incorporating a third surface partially transmissive reflector

An electrochromic mirror for use in a rearview mirror assembly having an electronic device positioned behind the electrochromic mirror for selectively projecting and/or receiving light therethrough, said electrochromic mirror comprising:

• front and rear spaced elements, each having front and rear surfaces and being sealably bonded together in a spaced-apart relationship to define a chamber;
• a transparent first electrode including a layer of conductive material carried on a surface of one of said elements;
• an electrochromic material contained within said chamber;
• and
• a second electrode overlying said front surface of said rear element in contact with said electrochromic material, said second electrode including a reflective layer of reflective material and a coating of a material that is at least partially transmissive and is disposed over substantially all of the front surface of said rear element, wherein said second electrode includes a region in front of the electronic device that is at least partially transmissive.

• a transparent first electrode including a layer of conductive material carried on a surface of one of said elements;
• and
• a partially transmissive, partially reflective second electrode disposed over substantially all of said front surface of said rear element, said second electrode including a transparent coating applied over a surface of said rear element and a thin reflective layer of silver or silver alloy applied over said transparent coating, said second electrode having a reflectance of at least about 35 percent, a transmittance of at least about 5 percent in at least portions of the visible spectrum, and a C* value of less than about 20.
